2,3-Dimethoxy-6,7-dimethyl-4-propyl-1-naphthoic acid CAS 213971-46-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,3-Dimethoxy-6,7-dimethyl-4-propyl-1-naphthoic acid.

2,3-Dimethoxy-6,7-dimethyl-4-propyl-1-naphthoic acid (CAS 213971-46-1), molecular formula C18H22O4 and molecular weight 302.36 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, 2,3-Dimethoxy-6,7-dimethyl-4-propyl-1-naphthoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 302.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 2,3-Dimethoxy-6,7-dimethyl-4-propyl-1-naphthoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
